I'm getting older, turning 40 this year. I had a period where I thought each expedition had to be something harder, something faster. But you can't go on like that, or you're going to die.

The goal is not to solo. Of course, it is possible to move fast in alpine style also with a partner. I just need the right partner.

Everest is how it is right now. We have to fix ropes up there; we have the commercial expeditions. If you don't like that, go on another mountain or choose another part of the mountain. There's still space for everybody.

Of course I climbed Everest without oxygen, but it's not the end of the story for me. The summit itself is not what counts. It's how'd you get there, what'd you climb, and there are really great opportunities to climb on this mountain. It's a beautiful place.

It's amazing how people will give when you don't ask. Many of them send money because they believe in the message.

I like the strategy of finding great entrepreneurs early, giving them some money, helping them a little - perhaps not as much as we would a regular core investment.

I can kind of make money through my other passion, which is brewing, and that's a pretty stable business, and it would free up my timeslot to take roles that I really liked and that I thought were interesting.

Kids are taking music for free all the time. They have Spotify, Pandora... The record companies aren't making the kind of music that they used to make. Artists make their money on tours, not from album sales.
